Quanta Computer has showcased a touch screen technology that will work with Microsoft's Windows 7 operation system.

The technology does not use capacitive or resistive touch panels, and instead it places cameras on the top edge corner of monitors. The two cameras will locate user's finger position and transfer the mouse pointer to where the finger points at.

In addition to touch screen functions, the technology also features multi-touch functions similar to ones with iPhone. It also features functions such as picture rotation, zoom-in and zoom-out.
